Dear Fellow Contract Owner:

We are pleased to present this annual report for the Liberty Variable
Investment Trust -- Colonial Growth & Income Fund, Variable Series; Stein Roe
Global Utilities Fund, Variable Series; Colonial International Fund for Growth,
Variable Series; Colonial U.S. Stock Fund, Variable Series; Colonial Strategic
Income Fund, Variable Series; Newport Tiger Fund, Variable Series and Liberty
All-Star Equity Fund, Variable Series -- and the SteinRoe Variable Investment
Trust -- Stein Roe Special Venture Fund, Variable Series; Stein Roe Growth
Stock Fund, Variable Series; Stein Roe Balanced Fund, Variable Series; Stein
Roe Mortgage Securities Fund, Variable Series; and Stein Roe Money Market Fund,
Variable Series. In the following pages, we will provide you with an overview
of the economic events that occurred over the past year and explain how we
positioned the funds to respond to these events.

Stocks Continued Their Surge

Coming out of the 1996 bull market, the stock market continued its upward
climb, with the Dow Jones Industrial Average (DJIA) setting new record highs on
nearly half the days in January 1997. Market strength continued throughout the
first quarter, buoyed by healthy economic growth, strong corporate profits and
low inflation. Continued strength in net new subscriptions to mutual funds --
partially reflecting the increasing commitment to stocks on the part of the
80-million-strong contingent of baby boomers -- also fueled the market's
growth. Now between 35 and 50 years old, baby boomers' appetite for investing
reflects their awareness of the increased savings and capital accumulation
they'll need for retirement.

  Concern about slowing earnings momentum, however, prompted many investors to
shy away from smaller growth stocks in favor of the relative liquidity and
predictability of large-cap stocks. By March 1997, investors had begun to
realize that the steady bull market could be buffeted by stepped-up
inflationary pressures resulting from too-strong economic growth, too-low
unemployment and rising wage rates. As a result, the Federal Reserve sought to
put the brakes on the economy, raising the federal funds rate by one-quarter
percentage point to 5.50 percent in late March.

  Although many market watchers expected this rate hike, markets stumbled
enough to offset much of the gains achieved in the first weeks of the year.
Nonetheless, the Standard & Poor's 500 Index ended the first quarter with a
modest 2 percent gain.

  After Federal Reserve Chairman Alan Greenspan took the podium in May,
reporting that economic growth was firmly under control, it appeared that
concern over inflation was no longer an issue at the front of investors' minds.
In fact, in the second quarter, the S&P 500 enjoyed a near-record run,
returning 17 percent. While the strongest gains still belonged to larger-cap
stocks, the pendulum began to swing back for small-caps during the quarter.
After months of being passed over, small-cap stocks were attractively priced.
This, coupled with solid profits, sparked a rally among smaller-cap stocks in
the waning weeks of the second quarter of 1997. News of a potential balanced
budget, strong profits reports in May, and Greenspan's optimistic read on the
economy helped buoy stock and bond prices.

  In July, at the beginning of the third quarter, large-cap stocks continued
their upward surge, boosted in part by strong global economies and reports of
greater-than-expected earnings. The DJIA reached a new high, with the blue-chip
index's performance representing its largest-ever point gain for any month in
its 101-year history. In fact, the DJIA cleared 8000 for the first time ever.
Also in August, the government passed the Taxpayer Relief Act of 1997. The
first federal tax cut in 16 years, the act includes a number of provisions
benefiting investors nationwide.

Asia Feints . . . and America Blinks

International markets had a mixed first half of the year with some markets
producing strong growth and others reflecting currency pressures. During this
time, the U.S. dollar strengthened against local currencies. Overseas markets,
and particularly Asia, disappointed for the most part in the third quarter,
primarily driven by a weak Japanese economy and the devaluation of several
Southeast Asian currencies.

 Excess debt, overcapacity and what may have been unwise economic and fiscal
policies sparked this devaluation. The resulting currency crisis struck many
Southeast Asian economies and then sparked a surprisingly severe crash in Hong
Kong. By the fourth quarter of 1997, this sequence of events finally unnerved
investors in developed countries. The result: sharp declines in all of the
major markets, including the United States. Stocks fell more than 550 points in
one day of trading on Oct. 28, 1997.

  The currency crisis in Asia stabilized somewhat in December, with the
International Monetary Fund providing resources to South Korea, and several
other governments proposing plans to get their economies to a more healthy
state. While it appears that these countries are addressing their severe
economic problems, we expect that for certain countries, the path to recovery
will be long and difficult.

 The International Monetary Fund's actions, coupled with strong domestic
growth, helped give investors the confidence to support a recovery in U.S.
stock markets. As a result, December gains concluded the third year in a row in
which the S&P 500 logged an overall gain of more than 20 percent. In fact, the
S&P 500 Index closed 1997 with a 33.35 percent return, while the DJIA posted a
24.91 percent return.

  The biggest market story of the fourth quarter, of course, was the change of
fortune that buffeted emerging markets. Emerging markets -- which are
concentrated primarily in Asia -- experienced major market downturns. The MSCI
EM Index posted a loss of 19.18 percent for the fourth quarter of 1997; it was
down by 13.45 percent for the year.

Good News in the Fixed Income Market

An excellent year for bonds rounded out a strong year for domestic markets
overall. Bonds performed particularly well in the latter part of 1997, as
rising bond prices drove the yield on the 30-year Treasury bond to 5.92 percent
on Dec. 31, 1997 -- its lowest point since January 1996. Investors turned to
bonds to avoid what they judged to be an overvalued stock market and to profit
from a possible drop in interest rates. In addition, with the United States
looking at a possible budget surplus in 1998, investors acted to take advantage
of a potentially more limited bond supply. The strong dollar encouraged foreign
investors to purchase U. S. bonds, which also fueled bonds' upward surge.

Summary

The strong year in large-cap domestic companies continued to produce healthy
equity markets in the United States. Growth oriented mutual funds benefited
accordingly. Likewise, fixed income funds benefited from the U.S. bond market's
strong showing. The small-cap equity market had a harder time this year as
investor favor trended toward large-cap growth companies, which tend to have
more stable earnings. International markets -- particularly Asia -- struggled
amidst the currency crisis that struck in the latter part of the year. Money
market fund yields reflected a steady year in money markets as interest rates
remained fairly stable.

Going Forward

The last several years have been a great golden era for the United States. The
strong economy of the past few years provided an environment in which U. S.
investors had the ability to achieve record gains. While disruptions and
dislocations in Southeast Asia may have some overlapping effects on the United
States, we are hopeful that the impacts on our economy, and the profits of U.S.
corporations as a whole, will not be major. What's more, we anticipate any ill
effects on other developed Western economies to be somewhat mild over the next
several quarters. As a result, we hope for a continued strong U.S. economy, and
a favorable investment environment, in coming months.

The Basics

Although no one can predict what might happen to the markets in the future, we
believe investors must understand the factors that move the markets, not just
to profit from them, but to gain the patience to ride out short-term
volatility. As always, no matter what direction you think the economy is
heading, it's important to remember the basics. Think long term and re-evaluate
your investment portfolio from time to time to make sure it continues to match
your goals, risk tolerance and time horizon.


Sincerely,

/s/ Richard R. Christensen

Portfolio Managers' Discussion
     John Lennon and Gordon Johnson are portfolio co-managers for Colonial
Growth and Income Fund, Variable Series, and vice presidents of Colonial
Management Associates, Inc.


What was the investment environment for stocks during the year?
     Over the past 12 months, there have been strong gains in almost all types
of equities, marked by pockets of volatility in March, August and October.
Throughout the year there were definite changes in the sectors that were
performing well. During the first half of the year, large capitalization
stocks, such as those in the Standard & Poor's 500 (S&P 500) Index, were
strong. In the second half of the period, middle capitalization stocks as
represented by the S&P Mid-Cap Index, outperformed large caps. Growth and value
stocks also performed differently during the year. Growth stocks outperformed
over the first six months, followed by a second half in which value stocks led
the way. Despite these variations, over the year as a whole, mid-cap and
large-cap stocks offered about the same returns, while growth stocks
outperformed value stocks.

What is your current investment strategy?
     By expanding our definition of value investing, our current strategy
allows us to more broadly diversify the portfolio. This New ValueTM perspective
focuses on a stock's value relative to others in its industry, rather than on
an absolute measure of value. Our equity holdings fall into three categories:
stocks that offer value; defensive stocks, which are more resilient in down
markets; and stocks that offer growth at a reasonable price.

What is your market outlook for the Fund?
     Despite the recent volatility in the stock markets, both here and abroad,
the U.S. economy remains sound, which bodes well for domestic stocks. The
Fund's well diversified portfolio should continue to benefit the Fund in the
future.

Dear Contract Owner:
     Stein Roe Global Utilities Fund, Variable Series seeks current income and
long-term growth of capital and income.


Fund Performance (as of December 31, 1997)

Inception Date ................................    7/1/93

   12-month total return ......................    28.75%
Net asset value per share on 12/31/96 .........   $10.70
Net asset value per share on 12/31/97 .........   $11.92

Portfolio Managers' Discussion

     Ophelia Barsketis and Deborah Jansen are portfolio
co-managers of Stein Roe Global Utilities Fund, Variable Series.


What was the environment like in 1997?

     Low inflation, low or falling interest rates in many areas of the world
and good economic growth, particularly in the U.S., Europe and Latin America,
combined to provide a favorable environment during most of the period. In the
U.S., those utility companies that cut costs and restructured their operations
to increase their competitiveness in advance of deregulation performed well. A
number of European utility stocks benefited from improving economic growth and
efforts to privatize many state-owned utilities. Latin American utilities,
which sought to fulfill pent up demand for basic electric and telephone
services also performed well.

     However, during the last several months of the year, a currency crisis in
Southeast Asia had a negative spillover effect on markets world-wide and
volatility increased. This event did not cause us to alter our investment
strategy--we maintained our conservative focus on a diversified group of
well-managed utility companies with good growth prospects in a variety of
countries. We believe that these market events may present the Fund with buying
opportunities over the near term and we will look closely at stocks in areas
where economic growth and market prospects appear favorable.

What impact did the sectors have on performance during the period?
     The portfolio is divided among the three major utility sectors:
electricity, telecommunications and gas/water. During the period, the
telecommunications sector offered the best value, often at the expense of the
electric sector, particularly in the U.S., where future deregulation and
increased competition limited upside potential. The portfolio benefited from
individual stock selection within the telecommunications sector.

What is your outlook for the year ahead?
     The utility supply and demand balance in many emerging nations is so tight
that any event that limits a utility's ability to service its customers has a
broad impact. Many utility services that we take for granted, such as running
water, private telephones and electricity, are less reliable in these countries
and utilities that are able to efficiently service this pent up demand should
do well.

     Elsewhere in the world, privatization and deregulation present utility
companies with new opportunities. We have already found value in the
independent power producer (IPP) sector of the electricity sector. As utility
companies worldwide are unable to generate sufficient electricity to keep pace
with growth in electric transmission needs, IPPs are able to fill this gap by
providing an independent source of electricity. The portfolio has owned IPPs,
and has avoided large exposure to traditional domestic electric utility stocks,
which we believe have less attractive earnings growth potential.

PORTFOLIO MANAGERS' DISCUSSION
Liberty Variable Investment Trust Colonial International Fund for Growth,
Variable Series
- --------------------------------------------------------------------------------

 
Dear Contract Owner:

     Colonial International Fund for Growth, Variable Series seeks long-term
capital growth, by investing primarily in non-U.S. equity securities. The Fund
is non-diversified and may invest more than 5% of its total assets in the
securities of a single issuer, thereby increasing the risk of loss compared to
a diversified fund.


Fund Performance (as of December 31, 1997)

Inception Date ................................   5/2/94
Assuming reinvestment of all distributions
   12-month total return ......................    (3.27)%
Net asset value per share on 12/31/96 .........    $1.96
Net asset value per share on 12/31/97 .........    $1.78

Portfolio Manager's Discussion

     David Harris is portfolio manager of Colonial International Fund for
Growth, Variable Series and vice president of Stein Roe & Farnham Incorporated.
He is also an investment management principal with Stein Roe Global Capital
Management, a division of Stein Roe & Farnham Incorporated.


What was your investment strategy like during the last 12 months?

     We remained committed to our value-oriented investment strategy. We
continued to favor smaller companies that are not closely followed by the
equity analyst community and that may be overlooked by many investors. These
stocks have a tendency to be underpriced relative to their operating and/or
financial strength.

     In the past, Southeast Asia was a source of attractively priced stocks
with long-term growth potential and strong financial and operating
characteristics. Earlier in the year as valuations became less compelling, we
reduced our positions in Southeast Asia. In our opinion, heightened investor
enthusiasm caused many of these stocks to shift from under- to over-valued.
However, as the Southeast Asian currency crisis emerged during the last part of
the period, dramatic reductions in share prices have made many of these stocks
attractive once again, despite near-term economic uncertainty.


     The Fund's strategy is to diversify across countries and industries to
reduce risk and invest in rapidly growing economies. The Fund's Asian exposure
has aided returns in the past because of the previous high economic growth in
the region. We believe that in the long term, Asia could recover and the
current slowdown is reflected in share prices. We also believe that small- and
middle-capitalization companies could continue to offer good investment
opportunities.


What is your market outlook?

     Our strategy focuses on buying shares of smaller, lesser known companies
with good long-term growth potential. We have a strong understanding of their
businesses and we purchase these companies at a price that suggests that
management can create shareholder value. Although we remain confident in the
long-term value of this strategy, it hampered the Fund's performance during the
past year.

PORTFOLIO MANAGERS' DISCUSSION
Liberty Variable Investment Trust Colonial Strategic Income Fund,
Variable Series
- --------------------------------------------------------------------------------

 
Dear Contract Owner:

     Colonial Strategic Income Fund, Variable Series seeks a high level of
current income, as is consistent with prudent risk and maximizing total return,
by diversifying investments primarily in U.S. and foreign government and high
yield, high risk corporate debt securities. The Fund may invest a substantial
portion of its assets in high yield, high risk bonds (commonly referred to as
"junk bonds") and therefore may not be suitable for all investors. Purchasers
should carefully assess the risks associated with an investment in the Fund.

</TABLE>

Portfolio Manager's Discussion
     Carl Ericson is portfolio manager of Colonial Strategic Income Fund,
Variable Series. Mr. Ericson is a senior vice president of Colonial Management
Associates, Inc. and director of the Taxable Fixed Income Department.


What was the Fund's investment strategy in 1997?


High Yield Corporate Bonds
     During the past 12 months, high yield corporate bonds benefited from the
stable economy and performed extremely well. Issuing companies were able to
refinance at relatively low interest rates. The market drew its strength from
the resulting cash flow and liquidity of these companies. Credit quality among
high yield bonds remains solid with default rates at historic lows of less than
2%.

International Arena
     In the international arena, the Fund invested primarily in European bonds.
However, the return on some of these--and other foreign government bonds--fell
below the return of U.S. Treasurys. Because we believed that investors were no
longer adequately compensated for some overseas investments, we eliminated
positions in South Africa and Italy and reduced holdings in other foreign
government markets.

U.S. Treasury Market
     Uncertainty in the world's markets, particularly in Asia, resulted in an
increased demand for the security of the U.S. Treasury market. This trend has
driven Treasury prices up and pushed yields down. The Fund's management also
turned to U.S. Treasurys in the face of concern about the future pace of
economic activity.

What is your market outlook?
     Our outlook for the coming year is positive. A modest interest rate
decline coupled with slowing growth in the economy should be favorable. We
remain committed to investing at least 20%, but not more than 50%, in each of
the three bond sectors--U.S. Treasurys, high yield bonds and international
bonds. These ranges allow us to seek out the best performing bonds, while
maintaining diversification. As the markets move, we assess the benefits and
risks and shift assets to the fixed income sector we believe has the most
promising combination of total return, yield and risk.

- --------------------------------------------------------------------------------

 
Dear Contract Owner:

     Colonial U.S. Stock Fund, Variable Series seeks long-term capital growth
by investing primarily in large capitalization equity securities.


Fund Performance (as of December 31, 1997)

Inception Date ................................   7/5/94
Assuming reinvestment of all distributions
   12-month total return ......................    32.23%
Net asset value per share on 12/31/96 .........   $14.22
Net asset value per share on 12/31/97 .........   $16.29

Portfolio Manager's Discussion

     Mark Stoeckle is portfolio manager of Colonial U.S. Stock Fund, Variable
Series. Mr. Stoeckle is a vice president of Colonial Management Associates,
Inc.

What was the investment environment like in 1997?

     The first half of the period was very strong for large company stocks.
However, the Asian currency crisis had a negative effect on the U.S. markets
during the second half of the period. On two consecutive days the Dow Jones
Industrial Average posted its largest single-day point decline in history,
followed by its largest single-day point gain. By the end of the period, large
company stocks regained most of their losses, illustrating their dominance over
smaller company stocks which continued to lag.

What was your investment strategy in 1997?

     We focused on high quality, large-cap stocks with good long-term growth
potential. Large companies continued to make productivity gains while focusing
on their core capabilities. Many companies are strategically better run today
than ever in their histories. We believe that these factors should have a
favorable effect on earnings growth in the future.

What sectors had an impact on Fund performance?

     Early in the period, we believed several technology stocks had become
overpriced and no longer offered attractive values. We sold several of our
technology stocks and invested the proceeds in financial service stocks that
offered greater potential for earnings growth. Shareholders benefited from this
strategic shift as technology stocks lost ground during the second half of the
period and financial institutions' outperformed the market.

What is your market outlook?

     The events of the past six months have left investors wondering what lies
ahead for the financial markets. The currency and financial crises in Asia
continue to play out and while we think that earnings growth may be affected,
it is too early to predict the extent of the impact. A number of factors have
led us to believe there is still room for large company stocks to generate
attractive earnings growth, although at a slower pace than over the last three
years. The economy is still growing, inflation is low and companies continue to
utilize technology to improve productivity and cut costs. However, we think
that stock selection will become more important in 1998 as a "rising tide" may
not continue to carry all stocks along with it. We believe we have a superior
approach to stock selection, as reflected by our core investment strategy and
are confident in our ability to continue to find attractively valued, high
quality stocks.

PORTFOLIO MANAGERS' DISCUSSION
Liberty Variable Investment Trust Newport Tiger Fund, Variable Series
- --------------------------------------------------------------------------------

 
Dear Contract Owner:

     Newport Tiger Fund, Variable Series seeks long-term capital growth by
investing primarily in equity securities of companies located in the nine
Tigers of Asia (Hong Kong, Singapore, South Korea, Taiwan, Malaysia, Thailand,
Indonesia, China and the Philippines).

Fund Performance (as of December 31, 1997)

Inception Date ................................        5/1/95
Assuming reinvestment of all distributions
   12-month total return ......................        (31.14)%
Net asset value per share on 12/31/96 .........         $2.52
Net asset value per share on 12/31/97 .........         $1.71

Portfolio Managers' Discussion

     Jack Mussey is president and chief executive officer of Newport Fund
Management, Inc. and portfolio co-manager of Newport Tiger Fund, Variable
Series. Tim Tuttle is managing director of Newport Fund Management and
portfolio co-manager of Newport Tiger Fund, Variable Series. While the Tiger
markets are subject to risks not associated with more developed countries, the
Fund's management team has more than 20 years of investment experience in the
region.

What was the Fund's strategy during the year?

     Our top-down investment approach, whereby we first select the high quality
countries followed by the high quality companies within those countries, has
served the portfolio well. We began the period with a sizable investment in
Hong Kong and Singapore. Both markets contain quality growth companies with
strong balance sheets--the kind of companies we favor. However, as the Thai
currency crisis emerged and unmasked a precarious banking system, we suspected
its potential spread to other markets and we shifted additional assets into
Hong Kong and Singapore.

     We reduced the number of stocks in the portfolio. These stocks represent
companies that we believe are among the best managed, best capitalized growth
businesses in Asia. In particular, we believe the utility sector has strong
growth potential. In Hong Kong, utilities enjoy a favorable regulatory
environment, as well as steady demand that we expect will increase as
residential building activity increases.

What is your market outlook?

     The magnitude of the Asian market and currency declines of 1997 indicate
serious financial problems, but we believe that this crisis should pass.
However, we are not comfortable predicting a quick turnaround in the seriously
weak economies of Thailand, Indonesia and South Korea. We question their
governments' will to take painful steps of economic restructuring that may
result in political or social unrest. On the other hand, we believe currencies
should stabilize as imports stagnate and exports grow. This could attract
foreign capital to help recapitalize the banking and industrial sectors of
these economies.

     We also believe that Hong Kong should benefit from its association with
China. China's huge economy is rich in terms of foreign reserves, high savings
and significant export activity. More importantly, we believe China has both
the political capability and the will to stimulate its economy. We expect lower
interest rates, more accessible credit and improved liquidity. In addition,
strong, ongoing productivity gains have made Chinese exports very competitive
with those of other nations. We anticipate that many Hong Kong companies will
experience increased business and asset flows from China's growing economy.

     In keeping with our quality philosophy, we intend to continue to emphasize
Hong Kong and Singapore in the portfolio. Weakness in these two markets over
the past six months can be largely attributed to a spillover of shaken investor
trust in the region. We believe that Hong Kong will continue to defend its
currency and that weakness resulting from market speculators will be dealt with
swiftly by the Hong Kong Currency Board. Over the long term, we believe that
Hong Kong will benefit from its commitment to its currency, a growing property
development sector and its close connection with China.

     We believe that the Tiger markets will once again generate attractive
returns over the longer term and we appreciate your patience and long-term
support.

Dear Contract Owner:

     Liberty All-Star Equity Fund, Variable Series seeks total investment
return, comprised of long-term capital appreciation and current income, through
investment primarily in a diversified portfolio of equity securities.

Fund Performance (as of December 31, 1997)

Manager's Discussion

     Liberty Asset Management Company ("LAMCO") is the manager of the Fund. No
one individual at LAMCO is responsible for LAMCO's investment management of the
Fund.

What is your investment strategy?

     The Fund's investment program is based upon LAMCO's multi-manager concept.
LAMCO allocates the Fund's portfolio assets on an approximately equal basis
among a number of independent investment management organization's ("Portfolio
Managers")--currently five in number--each of which employs a different
investment style, and from time to time rebalances the portfolio among the
Portfolio Managers so as to maintain an approximately equal allocation of the
portfolio among them throughout all market cycles.

     In LAMCO's opinion, the multi-manager concept provides advantages over the
use of a single manager because of the following primary factors:

     (i) Most equity investment management firms consistently employ a distinct
investment "style" which causes them to emphasize stocks with particular
characteristics;

     (ii) because of changing investor preferences, any given investment style
will move into and out of market favor and will result in better investment
performance under certain market conditions but less successful performance
under other conditions;

     (iii) Consequently, by allocating the Fund's portfolio on an approximately
equal basis among Portfolio Managers employing different styles, the impact of
any one such style on investment performance will be diluted, and he
investment performance of the total portfolio will be more consistent and less
volatile over the long term than if a single style were employed throughout the
entire period; and

     (iv) more consistent performance at a given annual rate of return over
time produces a higher rate of return for the long term than more volatile
performance having the same average annual rate of return.

     LAMCO, based on the foregoing principles and on its analysis and
evaluation of information regarding the personnel and investment styles and
performance of a universe of several hundred professional investment management
firms, has selected for appointment by the Fund a group of Portfolio Managers
representing a blending of different styles which, in its opinion, is
appropriate to the Fund's investment objective.

     LAMCO continuously monitors the performance and investment styles of the
Fund's Portfolio Managers and from time to time may recommend changes of
Portfolio Managers based on factors such as changes in a Portfolio Manager's
investment style or departure by a Portfolio Manager from the investment style
for which it had been selected, a deterioration in a Portfolio Manager's
performance relative to that of other investment management firms practicing a
similar style, or adverse changes in its ownership or personnel.

     The Fund's current Portfolio Managers are:

     J.P. Morgan Investment Management Inc.
     Oppenheimer Capital
     Palley-Needelman Asset Management, Inc.
     Westwood Management Corp.
     Wilke/Thompson Capital Management, Inc.

What is your market outlook?

     LAMCO and the Portfolio Managers generally believe that a continuation of
current favorable conditions for the domestic equities markets is possible,
even likely, with the turmoil in Asia being the most obvious "wild card" in
1998. More important, especially to variable annuity investors seeking to
accumulate retirement funds over a period of years, is the long-term outlook
for equities. And we continue to believe that a style-diversified portfolio of
quality equity securities is the best core holding for the long term.

operations and of changes in net assets and the financial highlights present
fairly, in all material respects, the financial position of each of the seven
series constituting Liberty Variable Investment Trust (the "Trust"), formerly
Keyport Variable Investment Trust, at December 31, 1997, the results of their
operations, the changes in their net assets and the financial highlights for
the periods indicated, in conformity with generally accepted accounting
principles. These financial statements and the financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Trust's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at December 31, 1997 by correspondence with the
custodian and brokers, and the application of alternative auditing procedures
where confirmations from brokers were not received, provide a reasonable basis
for the opinion expressed above.

 *** For the period from the commencement of operations July 5, 1994 to
     December 31, 1994.

 (a) Per share data was calculated using average shares outstanding during the
     period.

 (b) Total return at net asset value assuming all distributions reinvested.

 (c) Computed giving effect to Manager's expense limitation undertaking.

 
 (d) If the Fund had paid all of its expenses and there had been no
     reimbursement from the Manager, these ratios would have been 0.82%, 0.86%,
     0.94% and 1.60% (annualized), respectively.
 

 (e) The benefits derived from custody credits and directed brokerage
     arrangements had no impact. Prior years' ratios are net of benefits
     received, if any.

 
Federal Income Tax footnote (unaudited)

97.63% of the gain distribution recorded in December 1997 and paid in January
1998 was derived from long term gains.

 *** For the period from the commencement of operations July 5, 1994 to
     December 31, 1994.

 (a) Per share data was calculated using average shares outstanding during the
     period.

 (b) Total return at net asset value assuming all distributions reinvested.

 (c) Computed giving effect to Manager's expense limitation undertaking.

 (d) If the Fund had paid all of its expenses and there had been no
     reimbursement from the Manager, these ratios would have been 1.07% and
     1.64% (annualized), respectively.

 (e) The benefits derived from custody credits and directed brokerage
     arrangements had no impact. Prior years' ratios are net of benefits
     received, if any.

 (f) For fiscal years beginning on or after September 1, 1995, a fund is
     required to disclose its average commission rate per share for trades on
     which commissions are charged.

 
Federal Income Tax footnote (unaudited)

85.98% of the gain distribution recorded in December 1997 and paid in January
1998 was derived from long term gains.

                         NOTES TO FINANCIAL STATEMENTS



Note 1. Organization and Accounting Policies

 
Liberty Variable Investment Trust (the "Trust"), formerly Keyport Variable
Investment Trust, an open-end management investment company, was organized as a
Massachusetts business trust on March 4, 1993. At December 31, 1997 the Trust
consisted of seven series of Funds, each with its own investment objective,
policies and restrictions: Colonial Growth and Income Fund, Variable Series,
formerly Colonial-Keyport Growth and Income Fund ("Growth and Income Fund"),
Stein Roe Global Utilities Fund, Variable Series, formerly Colonial-Keyport
Utilities Fund ("Global Utilities Fund"), Colonial International Fund for
Growth, Variable Series, formerly Colonial-Keyport International Fund for
Growth ("International Fund for Growth"), Colonial Strategic Income Fund,
Variable Series, formerly Colonial-Keyport Strategic Income Fund ("Strategic
Income Fund"), Colonial U.S. Stock Fund, Variable Series, formerly
Colonial-Keyport U.S. Stock Fund ("U.S. Stock Fund"), Newport Tiger Fund,
Variable Series, formerly Newport-Keyport Tiger Fund ("Tiger Fund") and Liberty
All-Star Equity Fund, Variable Series ("All-Star Equity Fund") (individually
referred to as a "Fund", or collectively referred to as the "Funds"). Each
Fund's objective is as follows:
 

Growth and Income Fund seeks primarily income and long-term capital growth and,
secondarily, preservation of capital.

Global Utilities Fund seeks current income and long-term growth of capital and
income.

International Fund for Growth seeks long-term capital growth, by investing
primarily in non-U.S. equity securities. The Fund is non-diversified and may
invest more than 5% of its total assets in the securities of a single issuer,
thereby increasing the risk of loss compared to a diversified fund.

Strategic Income Fund seeks a high level of current income, as is consistent
with prudent risk and maximizing total return, by diversifying investments
primarily in U.S. and foreign government and high yield, high risk corporate
debt securities.

U.S. Stock Fund seeks long-term capital growth by investing primarily in large
capitalization equity securities.

Tiger Fund seeks long-term capital growth by investing primarily in equity
securities of companies located in the nine Tigers of Asia (Hong Kong,
Singapore, South Korea, Taiwan, Malaysia, Thailand, Indonesia, China and the
Philippines).

All-Star Equity Fund seeks total investment return, comprised of long-term
capital appreciation and current income, through investment primarily in a
diversified portfolio of equity securities.

 
Shares of the Trust are available and are being marketed exclusively as a
pooled funding vehicle for variable annuity contracts ("VA contracts") and
Variable Life Insurance Policies ("VLI Policies") offered by the separate
accounts of life insurance companies ("Participating Insurance Companies").
Certain Participating Insurance Companies are affiliated with the Investment
Adviser and sub-advisers to the Funds ("Affiliated Participating Insurance
Companies"). Such Affiliated Participating Insurance Companies are Keyport Life
Insurance Company ("Keyport"), Independence Life & Annuity Company
("Independence") and Liberty Life Assurance Company of Boston ("Liberty Life").
The Participating Insurance Companies and their separate accounts own all the
shares of the Funds. Liberty Advisory Services Corp. (the Manager) ("LASC"),
formerly Keyport Advisory Services Corp., provides investment management and
advisory services to the Funds pursuant to its Management Agreements with the
Trust. Colonial Management Associates, Inc. ("Colonial") provides sub-advisory
services to four Funds: Growth and Income Fund, International Fund for Growth,
U.S. Stock Fund and Strategic Income Fund. Stein Roe & Farnham Incorporated
("Stein Roe") provides sub-advisory services to Global Utilities Fund. Newport
Fund Management, Inc. ("Newport") provides sub-advisory services to Tiger Fund.
Liberty Asset Management Company ("LAMCO") provides sub-advisory services to
the All-Star Equity Fund. LASC has delegated various administrative matters to
Colonial. Colonial also provides transfer agency and pricing and record keeping
services to the Trust. Keyport Financial Services Corp. ("KFSC") serves as the
principal underwriter of the Trust with respect to sales of shares to
Affiliated Participating Insurance Companies. The Manager, Colonial, Stein Roe,
Newport, LAMCO, KFSC, Keyport and Independence are wholly-owned indirect
subsidiaries of Liberty Financial Companies, Inc. ("LFC"). Liberty Mutual
Insurance Companies ("Liberty Mutual") owns approximately 75% of the
outstanding voting shares of LFC. Liberty Life is a subsidiary of Liberty
Mutual.
 

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements. The preparation of
financial statements in conformity with generally accepted accounting
principles requires management to make estimates and assumptions that affect
the reported amounts of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements and the reported
amounts of revenues and expenses during the reporting period. Actual results
could differ from those estimates.

 
Valuation of Investments--Portfolio securities listed on an exchange and
over-the-counter securities quoted on the NASDAQ system generally are valued on
the basis of the last sale on the date as of which the valuation is made, or,
lacking any sales, at the current bid prices. Over-the-counter securities not
quoted on the NASDAQ system generally are valued at the latest bid quotation.
Long-term debt securities generally are valued on the basis of dealer-supplied
quotations or valuations furnished by a pricing service which may employ
electronic data processing techniques, including a "matrix" system to determine
the valuations. Foreign debt securities are valued at the current bid price
furnished by market makers. Foreign equity securities listed on an exchange are
valued on the basis

                   NOTES TO FINANCIAL STATEMENTS (Continued)

of last sale on the date as of which the valuation is made, or lacking any
sales, at the current bid prices. Forward currency contracts are valued based
on the weighted value of the exchange traded contracts with similar durations.
In certain countries, the Fund may hold foreign designated shares. If the
foreign share price is not readily available as a result of limited share
activity, the securities are valued at the last sale price of the local shares
in the principal market in which such securities are normally traded. Korean
equity securities that have reached the limit for aggregate foreign ownership
and for which premiums to the local exchange prices may be paid by foreign
investors are valued by applying a broker quoted premium to the local share
price. Securities for which reliable quotations are not readily available are
valued at fair value, as determined in good faith and pursuant to procedures
established by the Trustees. Short-term instruments with remaining maturities
of 60 days or less are valued at amortized cost unless the Trustees determine
this does not represent fair value.

Federal Income Taxes--The Funds intend to qualify as "regulated investment
companies" and as such (and by complying with the applicable provisions of the
Internal Revenue Code) will not be subject to Federal income tax on taxable
income (including realized capital gains) distributed to shareholders. By
making the distributions required under the Internal Revenue Code, the Funds
intend to avoid excise tax liability.

Organization Expenses--Costs incurred in connection with the organization and
offering of the Funds are being deferred and amortized over 60 months from the
date those Funds commenced business.

Delayed Delivery Transactions--Growth and Income Fund and Strategic Income
Fund may purchase or sell securities on a when-issued or forward commitment
basis. Payment and delivery may take place a month or more after the date of
the transaction. The price of the underlying securities and the date when the
securities will be delivered and paid for are fixed at the time the transaction
is negotiated. This may increase the risk if the other party involved in the
transaction fails to deliver and causes the Funds to subsequently invest at
less advantageous prices. The Funds identify securities as segregated in their
custodial records with a value at least equal to the amount of the purchase
commitment.

Expenses--Most expenses of the Trust can be attributed to a Fund. Expenses
which cannot be directly attributed are apportioned among the Funds in the
Trust.

Other--Security transactions are accounted for on trade date. Interest income
is recorded on the accrual basis. Dividend income is recorded on the
ex-dividend date. Net realized and unrealized gains (losses) on foreign
currency transactions include gains (losses) arising from the fluctuation in
exchange rates between trade and settlement dates on security transactions,
gains (losses) arising from the disposition of foreign currency, and currency
gains (losses) between the accrual and payment dates on dividend and interest
income and foreign withholding taxes. The Funds do not isolate that portion of
the results of operations resulting from changes in foreign exchange rates on
investments from the fluctuations arising from changes in market prices of
securities held. Such fluctuations are included with the net realized and
unrealized gains (losses) from investments. The Funds may enter into forward
currency contracts to purchase or sell foreign currencies at predetermined
exchange rates in connection with the settlement of purchases and sales of
securities. The contracts are used to minimize the exposure to foreign exchange
rate fluctuations during the period between trade and settlement date of the
contracts. The Funds may also enter into forward currency contracts to hedge
certain other foreign currency denominated assets. All contracts are
marked-to-market daily, resulting in unrealized gains (losses) which become
realized at the time the forward currency contracts are closed or mature.
Realized and unrealized gains (losses) arising from such transactions are
included in net realized and unrealized gains (losses) on foreign currency
transactions. Forward currency contracts do not eliminate fluctuations in the
prices of the Funds' portfolio securities. While the maximum potential loss
from such contracts is the aggregate face value in U.S. dollars at the time the
contract was opened, exposure is typically limited to the change in value of
the contract (in U.S. dollars) over the period it remains open. Risks may also
arise if counterparties fail to perform their obligations under the contracts.

Note 2. Fund Share Transactions

Each Fund's capitalization consists of an unlimited number of shares of
beneficial interest without par value that represent a separate series of the
Trust. Each share of a Fund represents an equal proportionate beneficial
interest in that Fund and, when issued and outstanding, is fully paid and
nonassessable. Shareholders would be entitled to share proportionally in the
net assets of a Fund available for distribution to shareholders upon
liquidation of a Fund.

Note 3. Security Transactions

 
Realized gains (losses) are computed on the identified cost basis for both
financial reporting and Federal income tax purposes.

Note 4. Distributions to Shareholders

The Funds intend to distribute as dividends or capital gain distributions, at
least annually, substantially all of their net investment income and net
profits realized from the sale of investments. All dividends and distributions
are reinvested in additional shares of the Funds at net asset value as of the
record date of the distribution. Income and capital gain distributions are
determined in accordance with Federal Income tax regulations, which may differ
from generally accepted accounting principles. The character of income and
gains to be distributed are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles.
Reclassifications are made to the Fund's capital accounts to reflect income and
gains available for distribution (or available capital loss carryforwards)
under income tax regulations. Accordingly, amounts as of December 31, 1997 have
been reclassified as follows:

instrument to maintain on deposit with the Funds' custodian bank or in the
Federal Reserve Book-Entry System securities in the amount at all times equal
to or in excess of the value of the repurchase agreement plus accrued interest.
The Funds may experience costs and delays in liquidating the collateral if the
issuer defaults or enters bankruptcy.
